How to inquire about the transfer of patent use right

The patent right can be transferred, but the right to use the patent cannot be transferred. The right to use the patent is determined by the contract or contract signed by the patentee and the authorized enterprise or individual. A third party may confirm with the patentee whether a specific company or individual has been granted the right to use the patented product, or require the patentee to issue an agreement or contract signed with the patentee.

The right to use a patent is the right granted by the patentee to a specific company or individual to use the patented product according to a certain agreement, and the licensee may not transfer the obtained patent right again. The right to use a patent can only be obtained through the authorization of the patentee.

Patent transfer refers to a contract in which the patentee, as the transferor, transfers the ownership or holding right of his invention-creation patent to the transferee, and the transferee pays the agreed price. The party who obtains the patent right through the patent right transfer contract becomes a new legal patentee, and may also conclude a patent transfer contract, a patent licensing contract and a patent application right transfer contract with others.

According to the Patent Law, if the right to apply for a patent is transferred, the parties concerned must conclude a written contract, which will take effect after it is registered and announced by the Patent Office. Written form, registration and announcement are the legal conditions for the entry into force of the patent application right transfer contract. Patent transfer contracts that are not signed in writing or registered and announced by the Patent Office are not protected by law.
